Hunter Valve SRV-101GT

The diaphram on this pictular valve seem to go out a lot. I have to reaplace the diaphram at least one a season. Is this normal and if so is there any way that I can just order the diaphram for this valve and not have to buy the whole valve?

No, that is not normal. What seems to be the problem with the diaphragm? Is is a tear, a whole, clogging or what? As far as the parts, you can just order the diaphragm, but for nearly the same price you can get all the parts in the purchasing the whole valve.

ON this particular valve, the diaphragm should fail in the open position if it has a hole or a tear in it. In this case where you stated the valve failed in the closed position, or barely leaking any water, makes me believe it is clogged. Take out the solenoid and make sure all the passageways are not blocked with debris. BE CAREFUL, don't poke it too much, one of the holes has a diaphragm under it.

What would cause it to tear or have a hole in it? How can I tell? Should I just take it out next time and try cleaning it up and put it back in instead of just automaticaly replacing it with a new one and throwing the old one away?

Do you have a well or is it municipal water?

It would not hurt to do a cleaning, especially on the white metering port.

A tear or hole can come from normal use and or from debris being in the line. I am at a loss as for why you keep having this problem, it seems that there should be a cause for this. These valves are pretty reliable and you should not have a problem for many years.
